Ruggles, Clive Ancient Astronomy: An Encyclopedia of Cosmologies and Myth. Joseph Von Fraunhofer discovered that when sunlight was scattered, large number of spectral lines were actually observed. Sometimes known as p In this sense the book is a tool one can use to predict the locations of the stars Compared to earlier astronomy the book is much more focused on serving as a useful tool than as presenting a system for describing the nature of the heavens. 2020.
